长轮询是一种有效的技术.我认为用会话运行民意调查是一个坏主意.因为会话仅适用于原始用户.你可以使用PHP cli运行你的长轮询.您可以检查您的中间件以仅允许cli进行路由轮询.你可以使用 pthreads
通过cli运行你的长轮询使用pthreads.而现在pthreads v3在CLI以外的任何地方都安全且合理地设计.你可以使用你的cron每一小时触发你的线程.然后在你的控制器中你需要存储$time = time();标记您的执行开始时间.然后创建dowhile循环以循环您的轮询过程.条件可以是($time> time()3600)或其他条件.内部循环你需要检查是否存在民意调查？如果是,则运行它.然后在内部循环线的底部你需要睡一段时间,例如2秒.

在你的background.PHP上(这个文件由cron执行)

<?PHP
error_reporting(-1);
ini_set('display_errors',1);
 
class Atomic extends Threaded {
    public function __construct($data = NULL) {
        $this->data = $data;
    }
 
    private $data;
    private $method;
    private $class;
    private $config;
}
 
class Task extends Thread {
 
    public function __construct(Atomic $atomic) {
        $this->atomic = $atomic;
    }
 
    public function run() {
        $this->atomic->synchronized(function($atomic) 
        {
            chdir($atomic->config['root']);
 
            $exec_statement = array(
                "PHP7.2.7",$atomic->config['index'],$atomic->class,$atomic->method
            );
 
            echo "Running Command".PHP_EOL. implode(" ",$exec_statement)." at: ".date("Y-m-d H:i:s").PHP_EOL;
            $data = shell_exec(implode(" ",$exec_statement));
 
            echo $data.PHP_EOL;
 
        },$this->atomic);
    }
 
    private $atomic;
}
 
$config = array(
    "root" => "/var/www/api.example.com/api/v1.1","index" => "index.PHP","interval_execution_time" => 200
);
 
chdir($config['root']);
 
$threads = array();
 
 
$list_threads = array(
    array(
        "class" => "Background_workers","method" => "send_email","total_thread" => 2
    ),array(
        "class" => "Background_workers","method" => "updating_data_user","method" => "sending_fcm_broadcast","total_thread" => 2
    )
);
 
for ($i=0; $i < count($list_threads); $i++) 
{
    $total_thread = $list_threads[$i]['total_thread'];
 
    for ($j=0; $j < $total_thread; $j++) 
    { 
        $atomic = new Atomic();
        $atomic->class = $list_threads[$i]['class'];
        $atomic->method = $list_threads[$i]['method'];
        $atomic->thread_number = $j;
        $atomic->config = $config;
 
        $threads[] = new Task($atomic);
    }
}
 
foreach ($threads as $thread) {
    $thread->start();
    usleep(200);
}
 
foreach ($threads as $thread)
    $thread->join();
?>

这在你的控制器上

<?PHP
    defined('BASEPATH') OR exit('No direct script access allowed');
 
    class Background_workers extends MX_Controller {
 
        public function __construct()
        {
            parent::__construct();
            $this->load->database();
            $this->output->enable_profiler(FALSE);
            $this->configuration = $this->config->item("configuration_background_worker_module");
        }
 
        public function sending_fcm_broadcast() {
            $time_run = time();
            $time_stop = strtotime("+1 hour");
 
            do{
                $time_run = time();
 
                modules::run("Background_worker_module/sending_fcm_broadcast",$this->configuration["fcm_broadcast"]["limit"]);
 
                sleep(2);
            }
            while ($time_run < $time_stop);
        }
    }
